CHALK-CUP.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed October 7, 1916. Serial No. 124,391.

To all whom it may concern:

Be it known that I, SAMUEL N. JnNsoN, a citizen of the United States, residing at Estancia, in the county of Torrance and State of New Mexico, have invented certain new and useful Improvements in Chalk- Cups, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in chalk cups and it is an object of the invention to provide a device of this general character of a novel and improved construction and which serves to effectively maintain a block or cake of chalk against removal after being applied thereto.

It is also an object of the invention to provide a novel and improved cup of this general character which is adapted to be anchored to a billiard table or the like so that the chalk applied thereto will not be displaced by the player or players.

The invention also, has for an object to provide a device of this general character which permits the chalking of a one with the elimination of the possibility of soiling the fingers or garments and whereby the life of the chalk is materially prolonged.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved chalk cup whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in elevation of a chalk cup constructed in vaccordance with an embodiment of my invention;

Fig. 2 is a view in top plan of the device as disclosed in Fig. 1;

Fig. 3 is a vertical sectional view taken through my improved cup as herein embodied; and

Fig. 4 is a vertical sectional view taken through the looking or holding cylinder herein included.

As disclosed in the accompanying drawings, my improved cup includes a tubular cylindrical body 1 having one end portion turned outwardly to afford an annular flange 2 provided with the perforate ears 3 through which suitable anchoring members 4:, herein disclosed as conventional screws, are adapted to be directed in order to anchor the device to the rail of a billiard table or other support.

The lower or inner end of the body 1 is adapted to be closed by the mat 5 of suitable material and which is held in assembled relation relative to the body 1 through the medium of the anchoring members 4 which also pass through said mat 5.

It will be perceived. that the mat 5 serves to protect the rail or other support against injury.

Snugly fitting within the body 1 is a sleeve 6 formed preferably of thin flexible steel and which has its lower or inner end portion provided with the outstanding annular flange or rim 7 adapted to extend within a gropve 8 produced at the lower or inner end of the body 1, whereby it will be perceived that after the body 1 has been anchored in applied position, the sleeve 6 is held against removal from within said body 1.

The sleeve 6 has struck therefrom a plurality of inwardly disposed prongs or barbs 9 which impinge or penetrate the chalk body or cake C when inserted therein, whereby said chalk is effectively held against removal.

The upper or outer end portion of the body 1 is provided with peripheral threads in order to permit the cap 10 to be detachably engaged with said body 1, said cap 10 partially intersecting the bore of the body 1 so as to overlie the outer or upper face 'of the chalk O to provide a means to further prevent said chalk from being removed.

It is to be noted that the bore of the cap 10 is inwardly tapered so as to effectively serve as a guide to properly direct the cut tip into engagement with the chalk C. The periphery of the cap 10 is provided with the outstanding bead 11 knurled or serrated in order to facilitate its application to or removal from the body 1.

It will be observed that when it is required to apply a body or cake of chalk C within my improved cup, it is necessary that the body 1' be removed as it is substantially impossible to remove said chalk through the upper or outer end of said body. By this construction it will be at once self-evident that the annoyance of having the chalk fall to the floor or being carried away by a player is eliminated.

It will also be noted that the bore of the cap is such as to permit the tip end of thought to be obvious that a chalk cup constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by-reason of the convenience andfacility with which it may be assembled, and it Willv also be obvious that my invention is susceptible of some change and modification Without material departure from the principles and spirit thereof and for this reason I do not ish to be under-stood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

1. claim:

1. A chalk cup including a tubular member, a' sleeve insertible within said tubular member and provided with inwardlv direeted'penetrating members, said sleeve being provided with means coacting with the tubular member for preventing removal of the sleeve through one end of the tubular member.

2. A'chalk holder comprising a tubular member provided adjacent one end with a groove, a sleeve insertible within said tubular member and provided with a flange seating within the groove of the tubular member, said sleeve being provided with engaglng means.

3. A chalk holder comprising a tubular body having one end portion provided with an outstanding flange to afford an anchoring means, a sleeveprovided with engaging means insertible within the tubular body, a removable cap engageable with the end portion of the tubular body remote from the flange, said cap being provided with an opening to afford a communication through the interior of the tubular member.

4:. A chalk holder comprising a tubular body having one end portion provided with an outstanding flange to afford an anchoring means, a sleeve provided with engaging means insertible within the tubular body, a removable cap engageable with the end portion of the tubular body remote from the flange, said cap being provided with an opening to afford a communication through the interior of the tubular member, and a mat for closing the opposite end of the tubular member.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
